DOT1L O-GlcNAcylation promotes its protein stability and MLL-fusion leukemia cell proliferation

open access: yesCell Reports, 2021
Summary: Histone lysine methylation functions at the interface of the extracellular environment and intracellular gene expression. DOT1L is a versatile histone H3K79 methyltransferase with a prominent role in MLL-fusion leukemia, yet little is known ...

Dek219 encodes the DICER-LIKE1 protein that affects chromatin accessibility and kernel development in maize

open access: yesJournal of Integrative Agriculture, 2023
Chromatin accessibility plays a vital role in gene transcriptional regulation. However, the regulatory mechanism of chromatin accessibility, as well as its role in regulating crucial gene expression and kernel development in maize (Zea mays) are poorly ...

Impaired Regulation of Histone Methylation and Acetylation Underlies Specific Neurodevelopmental Disorders

open access: yesFrontiers in Genetics, 2021
Epigenetic processes are critical for governing the complex spatiotemporal patterns of gene expression in neurodevelopment. One such mechanism is the dynamic network of post-translational histone modifications that facilitate recruitment of transcription

Cryo-EM structure of the nucleosome containing the ALB1 enhancer DNA sequence [PDF]

open access: yesOpen Biology, 2018
Pioneer transcription factors specifically target their recognition DNA sequences within nucleosomes. FoxA is the pioneer transcription factor that binds to the ALB1 gene enhancer in liver precursor cells, and is required for liver differentiation in ...

Progressive Phosphorylation Modulates the Self-Association of a Variably Modified Histone H3 Peptide

open access: yesFrontiers in Molecular Biosciences, 2021
Protein phosphorylation is a key regulatory mechanism in eukaryotic cells. In the intrinsically disordered histone tails, phosphorylation is often a part of combinatorial post-translational modifications and an integral part of the “histone code” that ...

The First Analysis of Synaptonemal Complexes in Jawless Vertebrates: Chromosome Synapsis and Transcription Reactivation at Meiotic Prophase I in the Lamprey Lampetra fluviatilis (Petromyzontiformes, Cyclostomata)

open access: yesLife, 2023
Transcription is known to be substage-specific in meiotic prophase I. If transcription is reactivated in the mid pachytene stage in mammals when synapsis is completed, then this process is observed in the zygotene stage in insects.

Heparin Attenuates Histone-Mediated Cytotoxicity in Septic Acute Kidney Injury

open access: yesFrontiers in Medicine, 2020
Histones are considered potential risk factors that contribute to the development of septic acute kidney injury (SAKI) by inducing apoptosis and inflammation.

Sample Volume Reduction Using the Schwarzschild Objective for a Circular Dichroism Spectrophotometer and an Application to the Structural Analysis of Lysine-36 Trimethylated Histone H3 Protein

open access: yesMolecules, 2018
With the increasing interest in scarce proteins, reducing the sample volume for circular dichroism (CD) spectroscopy has become desirable. Demagnification of the incident beam size is required to reduce the sample volume for CD spectroscopy detecting ...
